SD Card Settings Saving failed. Capture/replay in progress?

[Semper Talis]

Hi all,

I have an interesting problem to chew on.

I tried to make a backup for the SD-Card wich came with the kit.

I use a 256 MB card and formatted it to FAT16 .

Copy Paste from the original card.

First problem , 

the Altair does start in the default settings , Arduino programming port @115200 baud

The original card was set to A6/A7 and 9600 baud .

Is the settings file somehow hidden or why is it that the original settings are not copied ?

Second problem,

If I change the settings to A6/A7@9600 baud and to save it as default setting , I get:

Command: S

Save as config # (0=default): 0

Saving failed. Capture/replay in progress?

What is going on? I Just turn on the Altair , not touch any other switches than ON/Off and then STOP+AUX1 Up

Any help is much appreciated.

BTW I tried different sd-cards and computer ( OSX, Windows+Linux)

Update , I figured out the Altair is not recognizing the sd card correctly

When I go into the Manage Filesystem setting I get 

ID Type            Name        Size
-----------------------------------

Filesystem size: 16384 bytes
         in use: 4 bytes
      available: 16380 bytes

For the 256 MB card , so definitely not what I would expect.

You have to compile firmware using SDFat version 1.1.xx (check what version work for you) and SD card works fine.

Hi Antonio ,

You have to help a new Altair due owner here .

What do you mean with compile firmware ?

Do I have to reprogram the Arduino DUE ?

I got this kit just two weeks ago , I guess my firmware is the latest or are there any special settings I have to do ?

Any way I can verify what firmware is on my DUE ?

Regards, Wolfgang

Hi.

I have Altair 8800 simulator DIY version. I compiled the firmware with Arduino ide, but I installed an old version of SDFat library because the new ones not working with SD on Altair simulator.

Then. Open the Altair simulator project with Arduino IDE, install an old version of SDFat library for example 1.1.10, and try to compile if finally compile well upload firmware to Arduino DUE and check if now SD is recognized in not case try a different version of SDFat library.

I hope it could help you.

Sorry. I red again your message.

But that solution is if your SD card is not detected. In your case, maybe the setting is directly on Arduino DUE EPROM memory (not in SD) but I don't know about what could be happening.

Hi Antonio ,

Thanks for the explanation.

I will try it out , hope it helps.

I got one SD card working by now , a 2 GB card which I formatted on a Windows machine with the SD Formatter .

But no luck with my 256MB cards .

Not all low-capacity microSD cards are compatible with the Altair emulator. Very early microSD cards (commonly found in older cell phones) use an earlier controller implementation and may not initialize correctly. The supplied card is known to be compatible. As a rule of thumb, cards with the label printed in the "landscape" orientation (like the card on the right) are usually compatible, while cards with the label printed in the "portrait" orientation (like the card on the left) are almost always not going to work.  This is not a guaranteed way to determine if they'll work, but it's a good rule-of-thumb.

Sorry for the late reply , I thought I did so already .

Here the picture of the card I use .
